A question during a review had this sentence :
I wondered if I could replace the する here with いたす like in some of the examples given in the lessons about お〜する and いたす. An example for each:
ドアをお 閉めします 。
So I tried to put in :
But it got marked as incorrect. I also asked ChatGPT (I know it’s not really that reliable) and it also said it was wrong because it is a double-humble form. However, when I tried to check this sentence:
ChatGPT said it’s correct. The only difference between the two is that the former is a request while the latter is a simple declaration. They both use お and いたす.
Does that mean that while you can pretty much use いたす to replace する in お〜する, the exception would be when making a request?
Can いたす ever be used in a request? If not, is it because it refers to the actions of the speaker (or people within the speakers inner circle, like their company), but doesn’t that also apply to お〜する?
